After two days of building, nearly all the houses in the Jimmy & Rosalynn Carter Work Project have finished roofs, a good sign that the project is on track to complete all 100 houses, said Nevil Eastwood, the project’s director.

At midday Tuesday, Haitian President Michel Joseph Martelly arrived to tour the site and visit President Jimmy Carter and his wife, Rosalynn, who were building as Martelly’s motorcade arrived.

As they were exchanging greetings, President Carter invited singer Garth Brooks, who was working on a roof nearby, to meet Martelly, a former musician who was known as “Sweet Micky.”

Brooks hugged the Haitian president and said, “Thank you for making musicians around the world look smart,” drawing laughs from the crowd.

Martelly and the Carters then toured a Habitat house and had lunch together.

Day Two was another scorcher in the former sugarcane field where Habitat volunteers are laboring to build 100 houses in one week.

The on-site medical team is taking extra precautions to keep workers well-hydrated as they climb scaffolding and work on roofs in 90-degree heat.

After work, the volunteers got an unexpected treat, as Brooks and his wife, Trisha Yearwood, joined Habitat for Humanity International CEO Jonathan Reckford in the serving line at dinner. While Reckford dished out lasagna and chicken wings, Brooks served beans.

After dinner, Brooks and Yearwood took the stage to entertain the tired workers.
